C to a ratio for hexagonal close packed (c/a=1.63)

In this video, Parisa works through the calculation of the c:a ratio for the hexagonal close packed HCP) crystal structure. The final answer is c/a = (2sqrt2)/sqrt3 = 1.63.

In my country we are used to say things like: Vine buscando cobre, pero encontré oro. It means that I was looking for something but instead I found some other thing that overpass my expectations.
Congrats lady

Thank you for this video! I know that just the ending is wrong, but never mind that.

Pretty disgusting to see all these people commenting on her looks. It's really not relevant to the video and I'm sure she just finds you all pretty creepy.

the final is somehow
it should be c=(2√2)a/√3
